Do you think that I'm doing good?

Hello , My name is Mateusz (but u can call me Matt), I’ve made a nav bar which was aimed for responsive users. Im quite new for web dev and without following tutorials i just created this and my question is : Am i doing it right ? or i just made mistakes that will make the page working slower ?

Thanks for your feedback !

I like what you have made, but it’s not mobile friendly on my end and the width seems a little large.

Thanks for your respond ! Now I fixed that and made full-sized on mobile phones to check that u need to inspect in your browser and set mobile phone resolution
